MEREDITH MALLORY, OF URBANA, NEW YORK.

IMPROVEMENT IN THE METHOD OF PROPELLING BOATS.

Specication forming part of Letters Patent- No. 2,210, dated August 4,1841.

To all whom it may concern.-

Be it known that I, MEEEDITH MALLORY, of Urbana, in the county ofSteuben, State of New York, have invented a new and useful Improvementin the Propelling Power of Steamboats, for which I desire LettersPatent; and l declare that the following is a full and exactdescription.

The nature of my invention consists in placing tight bucket-wheels abaftthe paddlewheels to catch the water thrown up or elevated by thepaddles, the Weight of the water thus thrown up aiding the steam-powerin driving the paddle-wheels.

The annexed drawings represent a steamboat with a paddle and tightbucket-Wheels, (also showing the manner of gearing;) E, thepaddle-wheel; F, the tight bucket-Wheel with buckets of commonconstruction, corresponding in length to those of the paddle-wheels.

They are to be placed abaft thepaddle-Wheels from six inches to twofeet, varying according to the size of the wheels. The bucket-wheels maybe of the diameter of the paddle-wheels, less six inches added to thedistance the paddles are designed to run in the water, the top of thewheels to be on a level with the top of the paddle-wheels and the bottomsix inches above the surface of the water when the boat is loaded.

The gearing may be placed inside of theboat and the connecting-wheel soconstructed as to throw out or into gear at pleasure. One set ofspur-gears is sufficient for a boat, provided the water-wheel shaftsboth extend across the boat.

Now what I claim as my invention is The applying the water lifted orthrown up by the paddle-wheels of steamboats so as to produce anauxiliary propelling power, in the manner before described, or in anyway analogous thereto.

M. MALLORY.
